Is the secondary structure of any molecule or body the modification of the primary body?
Is the secondary structure of any molecule or body the modification of the primary body?
Yes in case of spermatogenesis. Spermatogenesis: It occurs in seminiferous tubules in the testes. These tubules contain the germinal epitheliumwhich is made of primordial germ cells and Sertoli cells. Formation of spermatids occurs in the following phases:
• Multiplication phase: When the male attains sexual maturity, the primordial germ cells divide several times to produce spermatogonia, which are the precursor of sperms.
• Growth phase: The spermatogonia grow to become primary spermatocyte by receiving nourishment from the Sertoli cells.
• Maturation phase: The primary spermatocyte divides twice; the first is meiotic (reduction) division, giving rise to two haploid secondary spermatocytes, which again undergo a mitotic division, giving rise to a total of four haploid spermatids.
